Description

Fruit Automatic Sorting Device Using Sensor

The present invention relates to a fruit sorting device that automatically sorts the fruit for shipment. More specifically, the size of the fruit passing through the top of the roller conveyor for sorting the introduced fruit into a sensor group consisting of a height sensor and a size sensor. The measured data is transmitted to the actuator supporting the tilting conveyor through a controller, and the actuator is configured to move the sorted fruit to a designated position by operating the tilting conveyor according to the received command. This can sort the fruit by size, high-speed sorting through the sensor, there is an effect that can be distributed to small farmers by producing at low cost instead of the conventional expensive sorting work.

Generally, after harvesting fruits, they are sorted according to the size, degree of color, and scratches, and graded according to the value of the product. As living standards improve and consumption of agricultural products increases, the demands of the market and consumers for quality products are increasing. In addition, in order to meet the needs of various consumer classes, various grading of products must be made, and quality grading refers to a standard that can be recognized by everyone, that is, a standardized standard. The standardization or standardization of these products facilitates judgments in transactions, correcting the order of market distribution and resolving disputes between producers, consumers, and distributors of quality and price. By clearly recognizing the quality differences of producers' products, they can be used as a measure for improving production technology. Screening is the standardization of products according to quality, and the standard of work is the screening standard, and the standards of domestic agricultural products are largely composed of grading standards and packaging standards, and the standards for the selection of domestic agricultural products are from the National Agricultural Products Quality Management Service. It is detailed in the enacted Agricultural Standards Standards Collection.

The quality of the product must be clearly defined so that the selected product is priced appropriately in any market and producers, distributors and consumers are not dissatisfied with the determined price. All factors that are the criteria when consumers select a product such as shape, size, color, uniformity, nutritional value, and taste are called quality factors, and the grade standard sets the grade of quality factors.

In general, the screening process involves two steps, a visual quality test and a short screening. The selected products are temporarily stored or immediately shipped to the market. Depending on the type of product, there may be a long-term storage after complete screening, or a preliminary screening luger site immediately after harvest, followed by a complete screening before shipment. The sorting of agricultural products is divided into size (weight) and quality sorting, and the weight sorting is done using a sorting machine, whereas the quality sorting is mostly done with the naked eye, which makes it difficult to subdivide the grades and standardize objective grade standards. The weight and size are mainly dependent on the mechanical selection. Fruits such as apples and pears have a certain proportion in weight and size. However, for products with a low correlation between heavy weight and volume (volume), uniform quality can be obtained by using a volume selector. Conventional sorting machine has a problem that the operation is mechanically low, the durability is low or the precision is low, and the more the subdivision of the sorting step, the higher the purchase price.

The present invention relates to an apparatus for automatically sorting fruit, and a conventional fruit sorting device is difficult to accurately classify the fruit according to the size and color of fruit according to the recent diversification of the consumption pattern. As a recent product corresponding to this, an image processing type sorter has been developed and distributed, but an image processing type sorting machine has a problem that a large sized sorting operation is slower than a conventional weight sorting and is expensive. Accordingly, an object of the present invention is to provide an automatic fruit sorting device using a sensor for measuring the size of the fruit and selecting the fruit based on the weight of the fruit.

In order to solve the above problems, the present invention moves the fruit through the rolling conveyor to automatically sort the size of the fruit, selects the size of the fruit on the top of the roller conveyor through the height sensor and size sensor, and measure the measured data To the controller. The controller is configured to transfer the measured data to the actuator supporting the tilting conveyor, and the actuator receiving the signal is configured to drive the tilting conveyor in accordance with a command to move the sorted fruit to a designated place.

The present invention is to measure the size of the fruit and not based on the weight selection of the fruit and to select, based on this, there is an effect to increase the speed of selection by measuring the fruit size at high speed through the sensor group irrespective of the position of the fruit, It is sold at a low price and can be easily distributed to small groups and farmers. It can also be used for sorting various kinds of fruits.
